CLEANING ATTACHMENT FOR HARVESTERS.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed April 19. 1907- Serial No. 369.133.

To all whom it may concern:

Be it known that I, CARL AMUNDsoN, a citizen of the United States,residing at Slayton, in the county of Murray and State of Minnesota,have invented certain new and useful Improvements in (leaning Attachmentfor Harvesters, of which the following is a specification, referencebeing had to the accompanying drawings.

Hy invention relates to improvements in harvesting machinery, andparticularly to binders and like machines; and an object of my inventionis to provide a machine of this character with an attachment for keepingits discharge arms clean of the straw and the like which collects uponthe arms in the ordinary use of the machine.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, Figure 1 shows so muchof a binder equipped with my attachment as is necessary to illustrate myinvention; and Fig. 2 shows my new attachment in perspective.

While only one discharge arm a is shown in the draw ing, it will beunderstood by all skilled in this art that there are two, side by side,and mounted upon the retary shaft b. V

My new cleaning attachment (Fig. 2) consists of the two-part arms 0, d,the front-board e and the claws f. By removing the bolts r the parts ofeach arm may be adjusted to shorten or engthen the arm. The frontboard eis formed with a series of holes g through which the front-board toadapt the device to discharge arms of various machines. Secured to thecross-bar 7c of the breast-plate support m are two clips n the strapmembers 0 of which carry each a lug or ear p in which is pivotallymounted the end of one of the side-arms c, do

As is clearly indicated by the dotted lines in Fig. l, the cleaningattachment of Fig. 2 is swung upwardly, as the discharge arms rotate;and the clawsf travel over the free end of the discharge arm, freeingthe latter from whatever straw may be clinging thereto. As the free endof the discharge arms move in their travel from under the claws, thecleaning attachment falls by its own Weight and is supported by thebinder frame g. In case it is desired not to use the device, it may beswung over out of the way of the other parts of the binder.

My cleaning attachment may be put upon any of the binders now inordinary use and upon the market.

I claim:

1. A cleaning attachment for harvesters consisting of a pair ofside-arms; a front board detachably secured to one of said side-arms andconnected with the other of said side-arms. said front-board being;formed witha plurality of holes; and a pair of claws detach-ably securedto said front-board and movable along the same from hole to holetherein.

2. A cleaning attachment for harvesters consisting of a pair of two-partside-arms, the parts of each side-arm overlapping and being adjustablewith respect to each other; a front-board formed with holes; boltspassing through a pair of said holes for securing said front-board to anend of each of said side-arms; and claws detachably secured to saidfront-board and movable along the same from hole to hole therein.

In testimony whereof I have hereunto set my hand at said Slayton thisthirteenth day of April/A. D. 1907, in the presence of the twoundersigned witnesses.

CARL AMUNDSON.
